Hello, my name is XXXXX XXXXX I will be helping you today.

 

From Volvo??? That's where I get mine when I've done this swap. Have you tried them yet?

Customer: replied 1 year ago.

tried getting information but get the run around and impossible to find a shop with a clue in a 200mile radius, contact info to a good tec line would be great or help finding the correct part #. Been fighting the problem for two years and at this point money is not an object

Jayson,

 

What engine are you trying to build? Are you trying to build a 5.7 GXI, a GSI, a GI?

 

Do you know what ECM you have now? Do you have the MEFI 4, or is it MEFI 5?

Customer: replied 1 year ago.

#s on top of computer reading top to bottom left to right are module ay emissions calibration(NNN) NNN-NNNN(NNN) NNN-NNNNemissions checksum $c5cee006e numbers on side of computer(NNN) NNN-NNNN470383 usa marine sae j1171 e1636001d 002187 5g the original motor was a 5.0gxi/osi I hope this helps u, if you could piont me in the right direction you would be my hero!!

Expert:  Jason replied 1 year ago.

Do you see MEFI on it anyplace?

 

What is the full model number on the engine, there would be a suffix at the end of GXI indicating its year.

Customer: replied 1 year ago.
The cover on top of the engine under the 5.0 category says GXi/OSi , under 5.7 it says Gi/OSi , the year make of the boat is 2006 , the tag on the block says type 5.ogxi-f
Expert:  Jason replied 1 year ago.
Got it. I think it's a MEFI 4 but I want to be sure. Is there any way you can get me a picture of your existing ECM?
Customer: replied 1 year ago.

sorry cant supply a pic as of right now but the full numbers on the 305 block prod no.3869309 type 5.ogxt-f ser XXXXXXXXXXX thats about as good as i can do for now

Expert:  Jason replied 1 year ago.

Jayson,

 

I got the pictures. The ECM you would want for the 5.7 engine if your going to use your same harness and injectors. (and I assume you are) is going to be Volvo part number 3863338

 

That should do it, but if I missed anything feel free to ask before doing the ratings.

Thanks in advance, and good luck!
